Interface Checked.Predicate<T,​E extends Throwable>

  • Type Parameters:
    T - Type of the predicate's parameter.
    E - Exception type that can be thrown by the body.
    All Superinterfaces:
    Enclosing interface:
    Checked<WT,​EX extends Throwable>
    Functional Interface:
    This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.

    public static interface Checked.Predicate<T,​E extends Throwable>
    extends Checked<Predicate<T>,​E>
    Like Predicate but with a body that can throw checked exceptions.
    • Method Detail

      • negate

        default Checked.Predicate<T,​E> negate()
        Evaluates this predicate on the given argument.
      • ederWrap

        default Predicate<T> ederWrap()
        Description copied from interface: Checked
        Wraps this Checked functional interfaces as its corresponding Java functional interface WT, which possibly does not allow checked exceptions.

        Checked exceptions of type EX may still, in reality, be thrown. This method is not intended to be called directly; it is used transparently by in(...), which passes the wrapper type into code that requires it, but re-exposes the original checked exception type to the compiler.

        Specified by:
        ederWrap in interface Checked<T,​E extends Throwable>
      • use

        static <T,​E extends ThrowableChecked.Predicate<T,​E> use​(Checked.Predicate<T,​E> o)
        Shapes a lambda or method reference into an instance of this functional interface.

        This is simply an identity function that can take the place of a more unwieldy cast.

        Type Parameters:
        E - Least upper bound of exception types o can throw.
        o - The implementing lambda or method reference.
